Not really a lot you can do , its life it happens , maybe it was robbed after being used and they didnt see !
If they are good workers why dock them to pay for it , you could end up with no blokes to use what poles you have left .
I used to chuck the pole on the roof in between jobs , I got to the next job and it wasnt there , it didnt fall off that i do know , it could have only been pinched whilst i collected £3.50 from the old dear i had just cleaned , Gone in 60 seconds , i should have made a film about it
But i sure was not sacking the bloke whos fault it was
